Discover How Low Zinc and a Copper Imbalance Can Impact Your Mood and Contribute to Anxiety with Expert Functional Medicine and Nutrition Practitioner Shelley Cavezza, PhD
Introduction: The Hidden Nutrient Connection to Anxiety
Anxiety is influenced by stress, lifestyle, genetics—and often, nutrient biochemistry. Emerging research shows that low zinc and an elevated copper-to-zinc ratio can affect brain chemistry, potentially contributing to heightened anxiety and mood dysregulation. Below, we explore how these two minerals affect neurotransmission and oxidative balance, and share practical strategies to restore balance.
Understanding Zinc and Copper in Brain Health
The Role of Zinc
- Neurotransmitter Regulation: Essential for producing and modulating serotonin and GABA, key calming neurotransmitters.
- Anti-Inflammatory: Zinc helps control inflammation, which is linked to anxiety and mood disorders.
- Cognitive Support: Supports neuroplasticity and brain-derived neurotrophic factor (BDNF) activity, bolstering cognitive clarity and emotional resilience.
The Role of Copper
- Enzymatic Functions: Vital for enzymes involved in dopamine and norepinephrine synthesis and cellular energy production.
- Oxidative Balance: When copper levels rise relative to zinc, oxidative stress increases, which may overstimulate excitatory neurotransmitters and disrupt mood regulation.
- Balance Is Key: Even normal copper levels can become problematic if zinc is low, shifting the zinc-to-copper ratio and affecting mood.
How Low Zinc & Copper Imbalance Fuel Anxiety
- Neurotransmitter Disruption
- Reduced Serotonin: Zinc deficiency impairs serotonin synthesis, and receptor sensitivity, contributing to low mood and anxiety.
- Compromised GABA: Zinc supports GABA’s inhibitory function; without it, neuronal excitability and restlessness can heighten anxiety.
- Oxidative Stress & Inflammation
- Inflammatory Cascade: A low-zinc/high-copper state can promote oxidative stress and elevate cytokines such as IL-6 and TNF-α, both linked to anxiety.
- Neuronal Impact: Chronic inflammation may impair synaptic signalling and disrupt the balance between glutamate and GABA, further destabilising mood.
- Stress Response Dysregulation
- Elevated Cortisol: Zinc helps modulate cortisol and the HPA-axis stress response. Low levels can lead to a heightened stress response and persistent anxiety.
Strategies to Restore Mineral Balance & Reduce Anxiety
- Nutritional Interventions
- Boost Zinc Intake: Include zinc-rich foods such as oysters, red meat, chicken, pumpkin seeds, legumes, and cashews.
- Balance Copper: Opt for whole foods rather than fortified or processed foods that may raise copper intake.
- Whole-Food Focus: A varied, unprocessed diet ensures you receive a spectrum of cofactors such as magnesium, vitamin B6, and taurine that support neurotransmitter balance.
- Targeted Supplementation
- Zinc Supplements: Zinc picolinate, citrate, or glycinate (under professional guidance) can correct deficiencies.
- Balanced Mineral Formulas: Some supplements combine zinc and copper in optimal ratios to avoid overcorrection.
- Lifestyle Modifications
- Stress Management: Mindfulness, meditation or yoga help lower cortisol and protect mineral balance.
- Quality Sleep: Essential for neurotransmitter synthesis, repair, and nutrient regulation.
- Regular Exercise: Moderate activity promotes endorphin release and supports metal homeostasis through improved circulation and metabolism.
- Comprehensive Evaluation
- Functional Medicine Assessment: Laboratory testing of zinc, copper and ceruloplasmin provides a clear picture for personalised planning.
Summary
Anxiety is multifactorial, but for some individuals, correcting zinc deficiency and rebalancing the copper-to-zinc ratio can make a noticeable difference. A personalised, functional medicine approach helps uncover biochemical drivers of anxiety – supporting steadier mood, clearer thinking, and enhanced emotional resilience
